Evolutionary restoration of fertility in an interspecies hybrid yeast, by whole-genome duplication after a failed mating-type switch

(A) Histogram of the distribution of synonymous site divergence (KS) values for 10,087 Z. parabailii ATCC60483 genes compared to their closest Z. bailii CLIB213T homologs. (B) Pie chart showing the proportions of genes classified into each category. The 2 largest categories refer to A-genes and B-genes that are in A:B pairs. “N” means genes for which no Z. bailii homolog was found or KS to Z. bailii exceeded 0.25. “As” and “Bs” indicate other A-genes and B-genes, as analyzed in panel C. (C) Breakdown of the numbers of genes assigned to the A- or B-subgenomes that are not in A:B pairs. See S1 Data for category counts and KS values for each gene.
